A new iPhone app is offering you the ultimate incentive not to miss that planned gym session to go to the pub; cash money.

The GymPact app for iPhone encourages users to outline their goals and then serve up their credit card details. Then, if you miss a gym session you're penalised anywhere between $5 and $10. That money will then be distributed to people who lived up to their commitments.

If you committed to more days, you'll receive a bigger percentage of the pool.

Last week, the company said that each work out was worth 73 cents to its users, while the developers keep a 30 per cent cut.

However, fakers beware, you can't just check off your work out and not go to the gym. Each user is required to check-in to a location for at least 30 minutes. Future iterations of the app will include run trackers for those adverse to the gym-bros grunting and groaning while spiking their hair.

“We decided to motivate people by having money on the line, rather than giving them money, which is a very radical departure from other motivational apps and programs,” said: Yifan Zhang, GymPact’s co-founder and CEO.

“We really think of what you have on the line as the number of days you’re committing. That’s really the focus of the program — how many days can we get you to go to the gym every week."
